Technical Field
[0001] This utility model relates to the field of base material testing technology, specifically a testing device for semi-rigid base composite materials containing basalt gravel. Background Technology
[0002] Semi-rigid base composite materials are road base materials with semi-rigid characteristics, formed by mixing graded aggregates (such as crushed stone and gravel) as the skeleton, inorganic binders (cement, lime, fly ash, etc.) and water as cementing materials, and then undergoing mixing, compaction and other treatments. They are commonly used composite materials for road engineering bases, and their stiffness and strength are between those of rigid and flexible materials. Semi-rigid base composite materials containing basalt crushed stone are road base materials with basalt crushed stone as the main aggregate skeleton, and have specific advantages in terms of strength, wear resistance, and durability.
[0003] Because of the high hardness and brittleness of basalt crushed stone, stress concentration points are easily formed at the interface bonding state with inorganic binders. Under repeated vehicle loads, micro-cracks are easily generated and gradually propagated. Cracks in the base layer will lead to obstruction of stress transmission, thereby causing reflective cracks in the surface layer and severely shortening the service life of the road. Therefore, it is necessary to test the crack resistance of semi-rigid base composite materials containing basalt crushed stone through testing equipment.
[0004] Existing crack resistance testing equipment suffers from variations in sample performance due to the mixing ratio of basalt crushed stone and inorganic binder. Slight differences in crushed stone gradation and binder content can lead to variations in sample properties. Furthermore, the test results for a single sample are easily affected by random factors, making it difficult to reflect the overall crack resistance of the material. Therefore, batch testing is necessary to reduce testing errors caused by individual differences. However, after sample testing, a large amount of residue and debris is generated. To avoid interference from these residues and debris in subsequent tests, manual cleaning is required, resulting in poor efficiency for testing multiple samples. To further improve the efficiency of sample testing, this paper proposes a testing device for semi-rigid base composite materials containing basalt crushed stone, which eliminates the drawbacks of existing devices.

[0021] In one embodiment, such as Figures 1-4 As shown, a testing device for a semi-rigid base composite material containing basalt gravel includes a base 1, a protective shell 6 installed on the top of the base 1, a guide rail assembly 7 installed inside the protective shell 6, a hydraulic push rod 5 installed on the guide rail assembly 7, a pressure block 4 fixedly connected to the output end of the hydraulic push rod 5, a feed inlet on one side of the protective shell 6, two protective windows 3 symmetrically rotatably connected inside the feed inlet of the protective shell 6, both protective windows 3 being rotatably connected to the base 1, and a collection mechanism for automatically classifying and collecting materials is provided on the base 1. The collection mechanism includes: a servo motor 2011 installed on one side of the base 1, a transmission rod 2010 fixedly connected to the output end of the servo motor 2011, and a discharge flap 204 fixedly connected to the side of the transmission rod 2010 away from the servo motor 2011. The discharge flap 204 and the transmission rod 2010 are rotatably connected to the base 1. In this embodiment, when in use, the sample for testing is placed on the upper surface of the unloading flap 204, and then the sample is conveniently clamped and centered by the collection mechanism, and the unloading flap 204 is supported and reinforced to effectively prevent the unloading flap 204 from swinging due to vibration during the sample testing process. Then, the protective window 3 is rotated to close the feed inlet, so as to prevent debris from splashing when testing the sample. Then, the hydraulic push rod 5 is activated to push the pressure block 4 to squeeze the upper surface of the sample. At the same time, through the cooperation with the guide rail assembly 7, the crack resistance performance of different parts of the sample can be tested. When the sample testing is completed, the above operation is reversed to easily release the clamping and fixing of the sample and simultaneously release the support and reinforcement of the unloading flap 204. Then, the servo motor 2011 is started to drive the transmission rod 2010 to rotate. At this time, the unloading flap 204 is flipped under the drive of the transmission rod 2010. Meanwhile, the tested sample and sample residues slide down the outer wall of the unloading flap 204 under the action of gravity. The sample can then be automatically cleaned and collected by the collection mechanism, thereby further improving the efficiency of sample testing. In one embodiment, such as Figures 1-4 As shown, the collection mechanism also includes a storage component mounted on the base 1; The storage assembly includes: a collection box 2014 slidably connected inside the base 1, the collection box 2014 being located below the unloading flap 204, a sliding groove for the collection box 2014 to slide at the junction of the base 1 and the collection box 2014, a support frame 2016 fixedly connected to the inner wall of the collection box 2014, a sieve 2015 provided on the upper surface of the support frame 2016, the sieve 2015 being slidably connected to the collection box 2014, and two handles symmetrically fixedly connected to the top of the sieve 2015.

Limiting components are provided on the unloading flap 204; A rotating component is provided on the base 1; In one embodiment, such as Figures 2-3 As shown, the limiting component includes two sets of limiting sliders 205 symmetrically fixedly connected to the outer wall of the unloading flap 204. A limiting groove is provided at the contact position between the base 1 and the limiting slider 205 for the limiting slider 205 to slide. The unloading flap 204 can be flipped and limited by the two sets of limiting sliders 205. In one embodiment, such as Figures 1-3 As shown, the rotating assembly includes: two bidirectional lead screws 203 symmetrically rotatably connected inside the base 1; a discharge flap 204 located between the two bidirectional lead screws 203; the discharge flap 204 located above the two bidirectional lead screws 203; a drive motor 201 is installed at one end of the base 1; and one bidirectional lead screw 203 is fixedly connected to the output end of the drive motor 201. The base 1 is equipped with a transmission assembly for driving the two bidirectional lead screws 203 to rotate synchronously; The base 1 is provided with a support component for providing stable support for the unloading flap 204; The transmission assembly includes: a transmission plate 2013 disposed at the end of the base 1 away from the drive motor 201; two transmission discs 2012 symmetrically disposed at the end of the transmission plate 2013 near the base 1; the transmission plate 2013 and the two transmission discs 2012 are eccentrically rotatably connected; the two transmission discs 2012 are respectively located at one end of two bidirectional lead screws 203; a transmission shaft 206 is fixedly connected to the end of each of the two transmission discs 2012 away from the transmission plate 2013; the transmission shaft 206 passes through the base 1 and is fixedly connected to the bidirectional lead screws 203; the transmission shaft 206 is rotatably connected to the base 1. The support assembly includes: two support rotating rods 209 symmetrically arranged inside the base 1; a discharge flap 204 located between the two support rotating rods 209; the two support rotating rods 209 located between two bidirectional lead screws 203; and two movable sliders 202 symmetrically rotatably connected to the outer walls of the two support rotating rods 209. The two movable sliders 202 are respectively sleeved on the outer walls of the two bidirectional lead screws 203, and the movable sliders 202 are threadedly connected to the bidirectional lead screws 203. A clamping assembly is provided on the base 1; The clamping assembly includes two clamping plates 208 symmetrically arranged on the upper surface of the base 1. The two clamping plates 208 are respectively located above two supporting rotating rods 209. Two connecting brackets 207 are symmetrically fixedly connected to the outer walls of the two clamping plates 208. The two connecting brackets 207 are respectively fixedly connected to two movable sliders 202. A linear slide groove is provided at the junction of the base 1 and the connecting brackets 207 for the connecting brackets 207 to slide. Through the cooperation of the rotating assembly, the transmission assembly, the support assembly and the clamping assembly, the sample can be clamped in the center while the unloading flap 204 is supported and reinforced, effectively preventing the unloading flap 204 from swaying due to vibration during the sample testing process.
[0022] The above embodiment discloses a testing device for semi-rigid base composite materials containing basalt gravel. In use, the sample to be tested is placed on the upper surface of the unloading flap 204. Then, the drive motor 201 is started to drive a bidirectional lead screw 203 to rotate. At this time, a transmission disk 2012 drives another transmission disk 2012 to rotate synchronously through the transmission shaft 206 and the drive of the bidirectional lead screw 203. At the same time, the other bidirectional lead screw 203 rotates synchronously through the transmission shaft 206 and the drive of the other transmission disk 2012. At this time, two support rotating rods 209 move closer to each other through two movable sliders 202 driven by the threads of the two bidirectional lead screws 203. At the same time, two clamping plates 208 move synchronously through the connecting bracket 207 driven by the movable sliders 202. Thus, the sample can be conveniently clamped and centered through the two clamping plates 208, thereby conveniently clamping and fixing the sample. During this process, the two support rotating rods 209 rotate due to friction with the base 1 when they move. When the support rotating rods 209 come into contact with the upper surface of the unloading flap 204, they rotate due to friction with the unloading flap 204. When the two clamping plates 208 clamp and fix the sample, the two support rotating rods 209 can support and reinforce the unloading flap 204, effectively preventing the unloading flap 204 from swaying due to vibration during sample testing. Then, the protective window 3 is rotated to close the feed inlet, thus preventing debris from splashing during sample testing. Then, the hydraulic push rod 5 is activated to push the pressure block 4 to squeeze the upper surface of the sample. At the same time, through the cooperation with the guide rail assembly 7, the crack resistance performance of different parts of the sample can be tested. When the sample testing is completed, the drive motor 201 is activated to reverse the above operation, which can easily release the clamping and fixing of the sample and simultaneously release the support and reinforcement of the unloading flap 204. Then, the servo motor 2011 is activated to drive the transmission rod 2010 to rotate. At this time, the unloading flap 204, driven by the transmission rod 2010, flips along the inner wall of the base 1 through the limit slider 205. Meanwhile, the tested sample and sample residues slide down the outer wall of the unloading flap 204 under the action of gravity. Inside the collection box 2014, the residue and debris of the sample can be sieved through the sieve 2015. Then, the servo motor 2011 is started to drive the unloading flap 204 to flip and reset, thereby automatically cleaning and collecting the sample. If multiple samples need to be collected separately, the collection box 2014 can be pulled out from the inner cavity of the base 1 when the next sample is to be tested. At the same time, the sieve 2015 can be moved by the handle, so that the tested samples can be conveniently collected separately, thereby further improving the efficiency of sample testing.

Therefore, the scope of protection of this application should be determined by the scope of the claims.
